Preface
With your new cordless telephone system you have
opted for lightweight and cordless telephoning, based
on the latest DECT/GAP technology. Therefore, you
are ensured of excellent sound quality and maximum
privacy. Eavesdropping or breaking in on line by
strangers is virtually impossible.
Your cordless telephone system can be extended to a
total of eight cordless phones. It is possible to have
an internal conversation using any two cordless
phones.
Your cordless telephone system has a CE marking
according to the guidelines of the European
telecommunications laws 73/23/EEC, 89/336/EEC
and 91/263/EEC. The CE marking corresponds to the
European marking law 93/68/EEC.

covered by the home base station or other telephone
system (check with your dealer). Outside this area,
you will lose contact with the system and the system
icon on the display will start flashing. The warning
light will flash and short, fast, warning beeps will be

Batteries
The cordless phone runs on three rechargeable batteries. You
can fully charge flat batteries by placing the cordless phone
in the home base station for 2.5 hours. Fully charged
batteries give you 12 hours of calling time or 110 hours of
stand-by time. The cordless phone displays a battery meter,
which shows the power remaining in the batteries.
The cordless phone runs on Nickel Metal Hydride
(NiMH) batteries. They can be recharged at any time.
Additionally, they are less damaging to the
environment than other batteries.
Reading the battery meter
When the batteries are fully charged the battery
meter on the cordless phone display consists of four
blocks. The number of blocks decreases as the
batteries discharge. If the batteries are almost flat, the
battery meter and the red light on the cordless phone
flash. An alarm sounds if there is less than 15 minutes
calling time left in the batteries.
Charging the batteries
Place the cordless phone in the home base station,
with the aerial upwards.

If the home base station green light is on or flashes
(and the battery meter on the display flashes), the
batteries are being charged. As soon as the batteries
are fully charged, the green light goes out and the
battery meter on the cordless phone stops flashing.
Changing the batteries
Rechargeable batteries have a limited life-span.
rc
Under normal conditions, the batteries for the
cordless phone will last for at least a year.
me
If the capacity of the cordless phone batteries
becomes too low, ask your dealer to replace the
batteries.
You can also replace the batteries yourself. Using a
Phillips screwdriver, remove the screw from the
battery compartment at the bottom of the cordless
phone. Replace old batteries with new batteries of
type NiMH AAA 450 mAh 1.2 V, with the flat side
of the battery facing upwards.
The batteries do not contain cadmium and are
therefore less damaging to the environment than
other rechargeable batteries. However, all batteries
should be treated as chemical waste.
